晶体熔化是最常见的自然现象,与材料的制备和性能密切相关。通常情况下,过冷液态可以亚稳态存在而不发生凝固,但实现高于熔点的过热却相当困难。因此过热成为学者们关注的一个基本科学问题。 世界各国学者近年来先后提出了多种晶体过热极限理论,中国科学院金属研究所材料科学国家重点实 Crystal melting is the most common natural phenomenon, and the preparation of materials and properties are closely related. Under normal circumstances, the supercooled liquid can exist metastable state without freezing, but to achieve over the melting point is quite difficult. So overheating has become a basic scientific issue that scholars pay attention to. In recent years, scholars all over the world have put forward a variety of crystal overheating limit theory, the Chinese Academy of Sciences Institute of metal materials science national focus
